Serial No. 376,242.

To all whom it may concern:

Be it known that I, ANNA L. GIBsoN, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a certain new and useful Improvement inI/Vater-Heaters, of which the following is a specification.

My invention relates to a new and useful improvement in water heaters,and has for its object to provide an exceedingly simple and effectivedevice by means of which water may be instantaneously heated while beingdrawn through a coil, and when not being drawn 03 the coil will continueto heat the water, setting up circulation in the tank. Thus when aconsiderable quantity of water is to be drawn off at a time the coilwill not be unduly lowered in temperature, as the water passingtherethrough having previously been heated will extract but littleadditional heat from the coil.

A further object of my invention is to provide anexceedingly effectiveform of burner by which gas flameswill be projected upon a coil from thetop and bottom, thus increasing the heating capacity of the coil.

With these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will describeits construction in detail, referring by letter to the accompanyingdrawing forming a part of this specification, in which Figure 1 is avertical section of the device. Fig. 2, a section at the line y'y ofFig. 1. Fig. 3 is a view in side elevation, partly in section, of theburner.

In carrying out my invention as embodied in the drawings, A represents areceptacle of any suitable size for containing the water to be heated,and beneath the bottom of this receptacle is located a coil pipe B, theinner end of which is passed through the bottom of the receptacle andcurved downward, as clearly indicated at C to form the downtake. Theouter end of this coil has connected therewith the tube D which leadsupward through the bottom of the receptacle, its upper end being curveddownward, and this pipe serves as the uptake.

E represents a faucet, which is connected with the outer end of the pipeand passes through the flange F, which serves as the base of thereceptacle inclosing the coil, the object of this faucet being to drawofi' any quantity of the water contained in the receptacle when desired.

The coil B is heated by means of a double circular burner G, a sectionthereof lying below the coil B, while another section thereof lies abovethe coil, and the flames issuing from these sections of the burner willimpinge against the coil and at the same time house the heat generatedtherefrom so as to impart the maximum heat to the coil. This burner maybe connected in any suitable manner to a gas supply through the pipe H.The inner wall of each section of burner G is provided with gasopenings, the openings of one section facing those of the other section.Water is admitted to coil B through downtake C, is heated therein andrises up through uptake D. Heated water is taken off through faucet E.

Having thus fully described my invention, what I claim as new anduseful, is

1. In combination with a receptacle, means for containing the water tobe heated, a burner consisting of a pipe and a pair of spaced oppositelydisposed circular sections receiving said water containing means in saidspace, the upper of said sections being formed with an opening, and apipe extending from said water containing means through said opening inthe upper section into said receptacle, said sections having gasopenings the openings of one section facing those of the other sectionso as to individually discharge the gas in said space.

2. In combination with a receptacle, a water coil beneath saidreceptacle having communication with the interior of said receptacle anda burner consisting of a single pipe having a pair of hollow spaceddisklike oppositely disposed sections receiving said coil in said space,said sections having openings formed therein the openings of one sectionfacing those of the other section.

In testimony whereof, I have hereunto affixed my signature in thepresence of two subscribing witnesses.

ANNA L. GIBSON.
